Hello everyone, I have the following errors on one of my clickhouse servers : 2020.12.16 10:23:20.590582 [ 2938445 ] {} <Error> void DB::BackgroundProcessingPool::workLoopFunc(): Code: 40, e.displayText() = DB::Exception: Checksum doesn'...
checksum问题 ck的性能很惊艳,但是很多细节实现的不够完善。 我们经常遇到checksum doesn't match问题。ck会不断的计算checksum,浪费一核cpu。 大家有没有遇到相同问题?没有断电,服务也没停过。用的是xfs文件系统,要改成ext4吗? github上有个个人写的修复工具bitflip。亲测好使。可以使用这个工具修复。 find xxx/...
三台服务器是一个etcd集群，然后基于flannel网络搭建的docker； 部署的服务node01上分别由config配置中心、discovery注册中心、gateway网关，剩下的服务都是基于前三个状态正常的情况下下才可以！ gateway在启动的时候，一会的down了，查看日志报错，大概是连接不到config配置中心读取不到配置！

insert_deduplication_token works on a partition level (the same as insert_deduplication checksum). Multiple partitions can have the same insert_deduplication_token.

LZ4 & ZSTD compression libraries were upgraded, checksum mismatch when having replicas with older versions are possibleIn the previous releases we recommended disabling optimize_on_insert. This recommendation stays for 23.8 as well as inserts into Summing and AggregatingMergeTree can slow down....
Check per-block checksum of the distributed batch on the sender before sending (without reading the file twice, the checksums will be verified while reading), this will avoid stuck of the INSERT on the receiver (on truncated .bin file on the sender). Avoid reading .bin files twice for batc...
